Each specified sub-block is correlated to a measurement position coordinate obtained from an external server by a measurement. The measurement position coordinate of each specified sub-block is stored in the storage device. The non-specified sub-block is directly or indirectly sandwiched by the two specified sub-blocks along a road. A measurement position coordinate of the non-specified sub-block is stored in the storage device when a distance between the measurement position coordinate and an estimation position coordinate of the non-specified sub-block is equal to or longer than a predetermined distance, and the measurement position coordinate of the non-specified sub-block is not stored in the storage device when the distance between the measurement position coordinate and the estimation position coordinate of the non-specified sub-block is shorter than the predetermined distance.

Storage device, navigation device, and map database creation method

A navigation apparatus has a display portion displaying a map that is controlled by a remote control as a manipulator. The remote control has a gravitation sensor. The gravitation sensor serves as a position detector to detect a three-dimensional coordinate set (x, y, z) of the remote control. A reduced scale for the displayed map is changed based on a displacement in z axis while the displayed map is moved based on a horizontal displacement in xy-coordinate plane. The remote control may move obliquely in a direction being neither parallel with z axis nor orthogonal to z axis, drawing a U-shaped locus. In this case, the reduced scale is designated as a subject reduced scale based on the lowest coordinate in z axis; the displayed map is moved based on a product obtained by multiplying the horizontal displacement by a unit distance according to the subject reduced scale.

Map display manipulation apparatus

An in-vehicle apparatus includes: a memory for storing a map data; a center communication element for obtaining a latest map data from a center; an inter-vehicle communication element for communicating with another in-vehicle apparatus; an input element for receiving an input signal of a specific area from an user; and a controller for setting the specific area as an initial main area. The inter-vehicle communication element receives another map data from another in-vehicle apparatus. The controller compares the map data with another map data. When another main area includes an area not included in the initial main area, the controller adds the area as a new main area, and updates the map data with another map data. The controller updates the map data corresponding to the initial main area with the latest map data.
